Using two 4-bit registers R1 and R2, and AND gates, OR gates, and inverters, draw one bit slice of the logic diagram that implements all of the following statements:

The control variables are mutually exclusive (i.e., only one variable can be equal to 1 at any time) while the other two are equal to 0. Also, no transfer into R2 is to occur for all control variables equal to 0.
